We all know that sitting is bad, especially when we do that very often. But what really happens to our bodies when we “hang” on the couch for hours?
After all, sitting can cause heart diseases. Muscles burn less fat, and the blood flows slower after long sitting, so fatty acids can clog the heart more easily. The long and often sitting has been associated with high blood pressure and elevated cholesterol, and many heart diseases.
Sitting may adversely affect the pancreas. The body produces insulin, the hormone which carries glucose to the cells for energy. However, the cells in the “lazy” muscles immediately respond to insulin and the pancreas produces more than necessary, which may lead to diabetes and other diseases. Studies have shown that people who sit more have a higher risk for cancer of the colon and breast. On the other hand, the regular movement creates production of natural antioxidants that kill cells which are potential producers of cancer.
When you stand or move, your abs keep you upright. But when you sit on a chair in a skewed position they are not used. Back muscles and “lazy” abs can alter the natural shape of the spine. Moreover, studies have shown that slight movement of the hips is the reason behind the frequent falling of the elderly.
Problems with legs
Sitting for long periods weakens blood circulation. This can cause swelling of the joints or thrombosis. Sitting may be weakened bones of the legs. With sitting, they become weaker, less frequent and weaker.
Problems with brain
Muscle movement fills the brain with fresh blood and oxygen, thereby causing secretion of chemicals for better mood and better concentration. When we sit for a long time, even the brain slows down.
Sitting can cause “rust” on the spine, or it may become less flexible. This can cause back pain.
The right way to sit
If you must sit regularly, do it the right way. Do not bend forward, the shoulders should be relaxed, keep your hands near the side of the body, let your feet be placed flat on the floor and provide support for the lower back.
Furthermore, getting up and moving are often recommended. Small breaks for exercise and stretching can prevent many problems.
